“…The corresponding values b using the values g = 0 and m = 1/ 2 [51] result in b = 3/2 and 7/4 for 2D and 1D systems, respectively. The present result b = 1.01 is closer to one expected for a 2D system and well comparable with values b = 0.9 ± 0.01, b = 0.6 ± 0.01 and b = 1.6 ± 0.01 reported for the structurally related antimonates Li 3 Ni 2 SbO 6 [53], Li 4 FeSbO 6 [28] and tellurate Li 4 NiTeO 6 [54].…”

The effect of antisite disorder in the layered sodium iron antimonate Na 4 FeSbO 6 was examined both experimentally and theoretically. The magnetic susceptibility and specific heat measurements show that Na 4 FeSbO 6 does not undergo a long-range antiferromagnetic order, unlike its structural analog Li 4 FeSbO 6 . The electron spin resonance yields the complicated picture of coexistence of two magnetic subsystems corresponding to two different Fe cation positions in the lattice (regular and antisite) and driving the magnetic properties of the Na 4 FeSbO 6 . This conclusion found perfect confirmation from both the Mössbauer and X-ray absorption data which

“…Here, we are dealing with an insulator, in which the asymmetry arises from the influence of non-diagonal elements of the dynamic susceptibility. This effect is often observed in systems with interactions of low symmetry, geometrical frustration and sufficiently broad resonance lines (B r  B) [46][47][48][49].…”

We present a comprehensive experimental and theoretical study of the electronic and magnetic properties of two quasi-two-dimensional (2D) honeycomb-lattice monoclinic compounds A 3 Ni 2 SbO 6 (A=Li, Na). Magnetic susceptibility and specific heat data are consistent with the onset of antiferromagnetic (AFM) long range order at low temperatures with Néel temperatures ~ 14 and 16 K for Li 3 Ni 2 SbO 6 and Na 3 Ni 2 SbO 6 , respectively. The effective magnetic moments of 4.3  B /f.u. (Li 3 Ni 2 SbO 6 ) and 4.4  B /f.u. (Na 3 Ni 2 SbO 6 ) indicate that Ni 2+ is in a high-spin configuration (S=1). The temperature dependence of the inverse magnetic susceptibility follows the Curie-Weiss law in the high-temperature region and shows positive values of the Weiss temperature ~ 8 K (Li 3 Ni 2 SbO 6 ) and ~12 K (Na 3 Ni 2 SbO 6 ) pointing to the presence of nonnegligible ferromagnetic interactions, although the system orders AFM at low temperatures. In addition, the magnetization curves reveal a field-induced (spin-flop type) transition below T N that can be related to the magnetocrystalline anisotropy in these systems. These observations are in agreement with density functional theory calculations, which show that both antiferromagnetic and ferromagnetic intralayer spin exchange couplings between Ni 2+ ions are present in the honeycomb planes supporting a zigzag antiferromagnetic ground state. Based on our experimental measurements and theoretical calculations we propose magnetic phase diagrams for the two compounds. 75.30.Kz; 75.10.Dg; 75.30.Gw; 75.30.Et

Na_1.5La_1.5TeO₆: Na⁺ conduction in a novel Na-rich double perovskite

et al. 2018

Increasing demand for lithium batteries for automotive applications, coupled with the necessity to move to large-scale energy storage systems, is driving a push towards new technologies and has seen Na-ion batteries emerge as a leading alternative to Li-ion. Amongst these, all solid-state configurations represent a promising route to achieving higher energy densities and increased safety. Remaining challenges include the need for Na+ solid electrolytes with the requisite ionic conductivities crucial for use in a solid-state cell. Here, we present the novel Na-rich double perovskite, Na1.5La1.5TeO6. The transport properties, explored at the macroscopic and local level, reveal a low activation energy barrier for Na+ diffusion and great promise for use as an electrolyte for all solid-state Na-batteries.
